Answer:

25 boys.

Step-by-step explanation:

To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.

If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x&lt;0.
Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

  • f(x) = 3^x
  • g(x) = 7^x

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

f(-1) = 3^{-1} = \frac{1}{3}

g(-1) = 7^{-1} = \frac{1}{7}

\frac{1}{3} > \frac{1}{7}, hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.

Given that lines b and c are parallel, select all that apply.
dangina [55]

Answer:

Angles 7, 2, and 6

Step-by-step explanation:

       Angle 7 is congruent by corresponding angles to angle 3.

       Angle 2 is congruent by vertical angles to angle 3.

       Angle 6 is congruent by vertical angles to angle 7, which is congruent to angle 3, so angle 3 and angle 6 must also be congruent.
